I'm not able to retrieve any custom fields on the Task object. I'm able to get Contact custom fields fine. These fields are included in a managed package, but I don't understand why the Contact fields are coming over fine, but not the Task fields. Below is the task object and field reference in the build file.
Task CustomObject
Task.Intervention_Task_Number__c CustomField
After trying to manually add the fields to the build file, I recieve an error "Entity Enumeration Or ID: bad value for restricted picklist field: Task
Any ideas? Thanks
